Drawability of Mild Steel Containing Small Amount of Nickel and Chromium

Abstract

The drawability of mild steels containing small amounts of nickel and chromium was studied. In the low carbon steel, nickel may be present in solid solution with iron, while chro-mium is present almost entirely as carbide. Thus the dependence of the difference in drawability upon the contents of nickel and chromium would be expected.
The results obtained are summarized as follows:
1) The mechanical properties, such as tensile strength and yield strength, were found to be improved with nickel content, but the dependence of these properties on the chromium content was indefinite.
2) The annealing texture of mild steel sheets showed no change with the nickel content, but the chromium content tended to retain the rolling texture.
3) The drawability of mild steel sheets was independent of the nickel content, but it had the tendency to deteriorate with the chromium content.
